Got my first gold of 2018 Saturday. (the 9k ring from my previous post I have decided is only plated.) It's from an old but still used hunted out beach i just went very slow and low hoping for targets. I think all four rings are old. The 14K nugget ring is 70's? the other 3 are 40's-60's? Maybe the silver ring is even older, the markings look very old to me. And what kind of stone or whatever it is do you think is in the silver ring?
